Porcelain \Por"ce*lain\ (277), n. [F. porcelaine, It.
porcellana, orig., the porcelain shell, or Venus shell
(Cypr[ae]a porcellana), from a dim. fr. L. porcus pig,
probably from the resemblance of the shell in shape to a
pig's back. Porcelain was called after this shell, either on
account of its smoothness and whiteness, or because it was
believed to be made from it. See {Pork}.]
A fine translucent or semitransculent kind of earthenware,
made first in China and Japan, but now also in Europe and
America; -- called also {China}, or {China ware}.
